Description:
Author(s): Xiao-yu Chen, Ping Yu, Li-zhen Jiang, and Mingzhen Tian We reduce the necessary and sufficient biseparable conditions of four-qubit cluster diagonal states to concise forms. Only 4 out of the 15 parameters are proved to be relevant in specifying the genuine entanglement of the states. Using the relative entropy of entanglement as entanglement measure, we... [Phys. Rev.
